How We Engage

An engagement model that fits how you work

Every engagement starts with a free consultation to scope the work. Pick the model that matches your stage — or we'll recommend one.

Fixed Scope

A defined deliverable at a fixed price. Best when requirements are clear and you want budget certainty from day one.

Well-defined MVPs, redesigns, and integrations

Time & Materials

Pay for the engineering time you use as scope evolves. Best for discovery-driven work where the roadmap adapts as you learn.

Evolving products and long-running builds

Dedicated Team

A vetted squad that plugs into your workflow and ships alongside you. Best for scaling capacity without the hiring overhead.

Team augmentation and sustained delivery

FAQ

FinTech Solutions — questions, answered

How much does a FinTech Solutions engagement cost?

FinTech Solutions is priced per engagement rather than off a fixed rate card, because scope, timeline, and team size differ for every client. After a free consultation we scope the work and propose one of three models — fixed-scope, time-and-materials, or a dedicated team — so you know the cost and commitment before anything starts.

How long does a typical FinTech Solutions project take?

Most FinTech Solutions engagements move from a discovery call to a scoped proposal within about a week, then into delivery in agile sprints. Smaller builds ship in a few weeks; larger platforms run for several months with working software delivered continuously, not just at the end.

Do you work with our existing team or take full ownership?

Both. DevenCodes can own FinTech Solutions end-to-end — discovery, design, build, and launch — or embed engineers who work as an extension of your in-house team. We adapt to your workflow, tools, and ceremonies rather than forcing ours.

Who owns the code and IP?

You do. On every FinTech Solutions engagement you retain full ownership of the source code, designs, and intellectual property we produce, with clean handover and documentation so your team can maintain and extend it independently.

How do we get started?

Book a free consultation and tell us about your goals. We'll assess fit, recommend an engagement model, and send a scoped proposal — usually within a few business days.
